Modbus: Wrong response from the slave

I am trying to write data to DVP28SS2 controller using minimalmodbus in ascii mode. I have received a responce from thr controller but it seems wrong. In particular bits, corresponding to slave address and the function code don’t match them.
The request is: 3A 30 31 31 30 30 30 32 38 30 30 30 31 30 32 30 30 36 34 36 30 0D 0A
(:01100028000102006460rn)
The response is: 3A 30 B1 39 30 30 B2 36 44 8D 0A
(:0±900²6Dx8dn)
Correct response for a request (as an example) should look like this:

Please, help me to find out what is going on…

I paste my code below

import minimalmodbus
import serial

D40 = 4096 + 40
instrument = minimalmodbus.Instrument(port = 'COM5',mode = 'ascii', slaveaddress = 1,  debug = True)  # port name, slave address (in decimal)

instrument.serial.baudrate = 9600        # Baud
instrument.serial.bytesize = 7
instrument.serial.parity   = serial.PARITY_EVEN
instrument.serial.stopbits = 1
instrument.serial.timeout  = 0.05         # seconds

## Write  ##
data_to_write = 100
instrument.write_register(registeraddress=D40, value=data_to_write,number_of_decimals=0)  

As a result I have recived:

MinimalModbus debug mode. Create serial port COM5
